Hi all,
We are building a MPPT charger for solar panel rated at 300 W, 15 V @ 20 A.
At the measuring part, we use a current transducer (ct) LEM HXS 20-NP/SP 3 (datasheet:http://www.farnell.com/datasheets/61020.pdf). We have it at the input and output. At the input has to measure about 20 A and at the output has to measure about 5-6 A. Somehow, we tested the ct and unfortunately the output of ct was not changing when the current was changing. We tested 3 same ct and those gave me the same output. Does anybody know why? Thank you in advance.
Regards,
Ben
